摘　　要：针对多功能酸洗缓蚀抑雾剂CQH-2对铝材缓蚀抑雾效果较差等问题，采用线性极化技术和失重法测定缓蚀效率，大气采样及酸碱中和滴定法测定抑雾率。通过优选，得到一种对铝材有很高缓蚀抑雾效果，同时又不影响其对碳钢、不锈钢等材料的高效缓蚀抑雾效果的新配方。并对其机理进行了初步探讨。：In order to solve the program about the bad corrosion and acid fog inhibit effect of the multifuction acid cleaning corrosion and fog inhibitor CQH-2 to aluminum, We mensurated the corrosion inhibit effects with the line linear polarity technique and weight loss measurement method, mensurated the acid fog inhibit effects with air sample and acid- alcali neutralize method.Through optimum seeking, we got a new upgraded composition of CQH-2 which have very high inhibit effects in aluminum-HCl system and have no influence on high inhibition to carbon steel and stainless steel in HCl. We also searched the mechanism of corrosion and fog inhibit effects.
